Freeman Custom Publishing! Smith and Michael P. Schenk is designed to provide students with a comprehensive introduction to the anatomy of the fetal pig. This full-color dissection guide and atlas gives the student carefully worded directions for learning basic mammalian. The laboratory guide directs students through a series of dissection activities for use in the lab accompanied by new, full color photos and figures. The guide can be used as a stand-alone dissection guide or in conjunction with any Anatomy and Physiology Laboratory Manual.
The Bohensky Dissection Serieshas been used successfully by more than , biology students nationwide. Each book in the series is designed to guide the student through the study of anatomical structures. The books do this through the use of clearly marked photographs and illustrations. Accompanying text offers the student both easy-to-follow.

The left lung contains three lobes and the right lung contains four. Each lung is located in a body cavity called a pleural cavity. You have already seen how the esophagus leads from the pharynx through the neck region.
Using a probe, trace follow the esophagus to the stomach. Identify the small intestine and large intestine.
Find the posterior part of the large intestine called the rectum and observe that it leads to the anus. Locate the cecum, a blind pouch where the small intestine joins the large intestine. Identify the liver. Lift the right lobe and find the gallbladder.
This structure stores bile produced by the liver. Find the bile duct that leads to the small intestine. The pancreas is located dorsal and posterior to the stomach. It extends along the length of the stomach from the left side of the body your right to the point where the stomach joins the small intestine. Lift the stomach and identify this light-colored organ. The spleen is an elongate, flattened, brownish organ that extends along the posterior part of the stomach ventral to above the pancreas.
The cecum is a blind pouch where the small intestine joins the large intestine. It houses bacteria used to digest plant materials such as cellulose. The cecum is large in herbivores but much of it has been lost during evolution in humans. The appendix in humans is the evolutionary remains of a larger cecum in human ancestors.
The drawing below shows some of the major arteries that carry blood to the body. Blood vessels that branch from the aorta carry blood to most of the body.
The pulmonary artery is capable of delivering a large amount of blood to the lungs but the lungs are not needed to oxygenate the blood of a fetus, so most of the blood is diverted to the aorta. This diagram shows that the ductus arteriosus connects the pulmonary artery to the aorta and diverts blood that would otherwise go to the lungs.
Shortly after birth, the ductus arteriosus closes and blood in the pulmonary artery goes to the lungs instead of the body. Blood passes from the left ventricle through the aortic arch and aorta to the body.
The first branch of the aorta is the brachiocephalic artery. The second branch is the left subclavian artery which goes to the left front leg. The right subclavian carries blood to the right front leg and the carotids carry blood to the head. The pericardium is a membrane that surrounds the heart and lines the pericardial cavity. It contains a lubricating fluid and isolates the heart from body movements such as the expansion and contraction of the nearby pleural lung cavity.
To view details of the aortic arch, ductus arteriosus, and pulmonary artery, it will be helpful to remove the left lung. With the left lung removed, the heart can be pushed to the right side to reveal the aorta and other blood vessels shown in the diagram below. Original work by Michael J.
